Weather in September

September's weather in Fuiloro, East Timor, signals the end of the city's dry season. A fresh air fills the city as the temperatures rise, and relative humidity subtly increases. As it is the last month of the dry season, the rainfall is slightly higher than August, but the quantity is still low. Only a meager 4mm (0.16") of average rainfall is recorded this month. It is worth noting, however, that the sunshine hours increase, making September relatively sunny.

Temperature

The onset of September manifests an average high-temperature of a still warm 29.8°C (85.6°F), demonstrating a minor variation from the preceding month. Fuiloro records a steady low-temperature average of 21.3°C (70.3°F) during September.

Heat index

For most parts of September, the heat index is computed to be a fiery hot 35°C (95°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

The average relative humidity in September is 72%.

UV index

The months with the highest UV index are January through March, September through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for ordinary individuals.
Note: The UV index of 7 during September translates into the following guidance:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. During bright days, sunglasses that offer UVA and UVB defense are recommended.
